Temporal and spatial variability of landscape ecological risk in the Yangtze River Midstream Urban Agglomeration in the context of climate change

Human and Ecological Risk Assessment An International Journal, Год журнала: 2025, Номер unknown, С. 1 - 30

The Yangtze River Midstream Urban Agglomeration is a pivotal economic zone in China. Over the past 35 years, climate change has increased ecosystem vulnerability and instability this area. Therefore, assessing landscape ecological risk (LER) vital for region. This study analyzed LER variations from 1985 to 2020 using statistical methods indices, forecasted changes 2025 2050 with multi-model meteorological data. Results show following: (1) indices have decreased over last notable shift high-risk medium-risk areas. High areas remained concentrated low-elevation, densely urbanized central regions, indicating severe damage compared high-elevation (2) Climate significantly impacts index, temperature exerting stronger influence than precipitation. Overall, decreases rising temperatures precipitation, though some cities exhibit opposite trends. (3) Future multi-Shared Socioeconomic Pathway scenarios suggest general decrease predominantly resulting low- zones. will persist low-elevation zones, particularly southern plains. Given high plains, timely governmental regulation control measures are essential ensuring ecologically sustainable development.

To address the ecological security issues in Songnen Plain, this study constructs pattern by using Multi-Criteria Evaluation Method, Minimum Cumulative Resistance (MCR) model, and Circuit Connectivity Model. Results show that: 1) The source areas were 66, 52, 56 blocks 2000, 2010, 2020 respectively, which are composed mainly of forests, water bodies, wetlands. distribution resistance values surface shows a gradually increases trend from to outward surrounding regions. high low value more dispersed, consisting with overall spatial distribution; 2) numbers corridors temporal declining 178 2000 159 reduction 645.46 km total length.

Research on Spatiotemporal Evolution of Land Use and Landscape Ecological Security in Mining Subsidence Area with High Groundwater Level

Polish Journal of Environmental Studies, Год журнала: 2024, Номер 33(5), С. 5577 - 5595

Опубликована: Май 23, 2024

Xuzhou used to be a significant coal resource-based city in eastern China and typical mining area with high groundwater level.Prolonged underground activities rapid urbanization have profoundly transformed its regional landscape pattern.Therefore, analyzing the laws of land use spatiotemporal evolution ecological security holds importance for sustainable development.Based on multi-period remote sensing data from 1990 2020, this study analyzed intensity changes transformation characteristics over 30-year period.On basis, status different periods was evaluated by Landscape Ecological Security Index.Lastly, spatial autocorrelation analysis conducted reveal overall local variations distribution security.The results indicate following: (1) Over course 30 years, due mining-induced subsidence water accumulation, increased 67.41%, exhibiting highest dynamic change use; construction came next, increasing 30.75%; cultivated declined most gently.(2) From 2010, displayed deteriorating trend, areas low were closely associated zones.From 2010 guided restoration plans, fragmentation patches decreased, leading evident improvements security.(3) The revealed positive correlation clustering areas.The high-high aggregation mainly distributed around land, while low-low primarily within zone.Overall, main factors influencing highwater-level area.In territorial planning, emphasis should placed connectivity diversity landscapes enhance offer essential information decision support governmental authorities planners, aiming achieve development.
